To all whom t may concern:

Be it known that I, JOHN MCE. AMES, of Dongan Hills, Staten Island, Richmond county, city of New York, and State of .N ew York, and being a citizen of the United Sta-tes, have invented certain new and useful Improvements in Car-Underframes, of which the following is a full, clear, and exact de scriptum. such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not .limited to the exact details of construction shown and described, as it is obvious that various modifications thereof will occur to persons skilled in the art.

This invention relates to improvements in underframes for railway cars and is designed especially for use with underframes of wood though it may be used with any suitable style of underframing.

The object of the invention is to produce.

an improved draft sill arrangement. which may be secured to and carried below such under-framing and preferably in -line with following description and claims.

Referring to the drawings, Figure l1 is a central longitudinal view showing the invention applied in position, the section being taken on line 1-1 of Fig. 5. Fig. 2 is a similar view showing a slightly modified form of construction. Fig. 3 is a transverse sectional view, the section being taken 011 line 3-3 of Fig. 1. Fig. 4 is a transverse sectional view, the section being taken on line 4--4 of- Fig. 2. Fig. 5 is a plan view showing the modification of Figs. l, 3., 7 and 9 in position. Fig G is a -plan View showing the modification of Flgs. 2, 4, 8 and 10 in position. Fig. 7 is a transverse sectional vew on line 7-7 of Fig. Fig. 8

is a transverse sectional View on line 8 8 of Fig. (5. Fig. 9 is a transverse sectional view on line 9-9 of Fig. 5. Fig. 10 is a transverse sectional viewon line 10-10 of Fig. 6.

.Referring to the parts: 1 indicates center sills: 2 side sills; 3 intermediate sills and 4 end sill, and as the device is duplicated at the other end of the car only an end fragment of the car is shown.

5 indicates generally the draft. rigging including spring 6, yoke 7 and follower stops 7 of any suitable detail construction adapted for the purpose. The style of draft rigging is not material, hence further description thereof i's not required.

In the construction illustrated in both modications the draft. sills hereinafter described pass rearwardly of and between the upper and lower bolster members 8 9 thereby forming struts for such holsters. EX- tending thence forwardly are the draft sills 1 0-10 said sills in Figs. 1, 3, 5, 7 9, comprising special rolled shapes having oppositely disposed integral flanges 11 at their upper sides whereby a considerable bearing surface is provided for the center sills. Projecting laterally and outwardly from the vertical websl l() are integral flanges 12 through which, and through the flanges 11 vertically above which, pass bolts 13 which extend though said center sills and serve as securing means for the said draftl sills. It is to be observed that there are no inwardly disposed flanges at the lower side of the -draft sills. Thus the entire space between their webs is available for the insertion of suitable draft. rigging which is supported in position in any desired manner, as by straps 14.

In Figs. 2, 4, 6, 8, 10 are shown draft sills of substantially Z shape wherein the up per flanges 15 project inwardly and the lower flanges 16 extend outwardly while the webs 10 thereof arevertical or nearly so. Tie straps 1T are riveted to the inwardly disposed flanges 11 ,and 15 and are secured` thereto by 'rivets 16 as shown while said tie straps extend laterally beyond the vertlcal webs of the draft sills in both modifications and in the modification of Figs. 2, 4, 6, '8 and 10 provide additional bearing surface for the center sills resting thereon. Thus I have provided separate draft sills of metal which are es ecially adapted for use WitlrwoodA under rames. Said draft sills being of metal and being carried under the center sills'may be 'substituted for wood-draft sills in case of repairs or renewal Vof such parts. It is to be understood. that the draft sills may terminate-short'of the bolster members Where it is advantageous to use a different type of bolster.

- In' the construction illustrated i wherein `the draft sillsextend through the holsters,

draft sill stops 18 are secured to the upper flanges of the draft sills and abut against the upper bolster member 8 at'eacli side thereof, said draft sill s'tops being secured to the draft sills by means of rivets 19 as shown. If desired the draft sills may lbe continuous from end to end of the car.

Havingtdescribed the invention, what I claim is:

l. a car underframe, the combination comprising end sills, wood center sills ex tending to said end sills and rolled, metallicdraft sills in a plane below said center-sills',

.' said draftsills havinginwardly disposed upper, flanges, vertical webs andA outwardly disposed lower flanges and securing means extending through said center sills andbutside of the webs. ofsaid draft sills.

2. In a car underframe,y the combination comprising end sills, wood center sills eX'- tending to said end sills and rolled, metallic draft sills in a plane'below said center sills,

said draft sillshaving inwardly.A and outwardly disposed upper flanges, vertical webs and outwardly disposed lower flanges and securing means extending through said center sills and outside of the webs of said draft sills.

In acar underframe, thel combination with holsters and wood center sills, of'd-raft sills if a'plane below said center sills' and forniL g struts for said holsters, said draft sills having integral inwardly disposed upper flanges, relatively vertical webs and outwardly disposed lower flanges and vertically disposed securing 'means passing through said center vsills-and said. lower flanges.

4. In a.. 'car underframe,'the combination.

with holsters-and wood center sills,.'ot1v draft sills in a. planebe'low said center sills and forming stru'ts for said holsters, said draft sills having integral inwardly and outwardly disposed ,upper flanges, relatively vertical webs and outwardly'disposed .lower fi-anges and vertically disposed securing 'means paf-3s ing through said center sills andsaid l?, ver

llanges 5'. In car underframe, the combination with holsters and wood center sills, of draft sills in a plane below said center sills and forming struts for said holsters, said draft sills having integral inwardly and outwardly disposedjupper flanges, relatively vertical webs and Voutwardly disposed lower anges 6. In a car.underframe,.the .combination with holsters and wood center sills, of draft .sills in a plane. below said-center sills and 1forming struts for said holsters, said draft' sills having integral inwardly and outwardly disposed upper llanges, relatively verticall webs and outwardly disposed lower flanges and verticallydisposed securing means pass- :ing through said center' sills and both outer flanges of said draft sills;

7. In a car underframe, the combination with .holsters and wood center sillsof4 draft sills in a plane below said center sills, said draft sills having integral inwardly and outwardly disposed upper flanges, relatively vertical webs and outwardly vdisposed lower flanges and vertically disposed securing means 'passing through saidcenter sills and 'with holsters and wood center sills, of draft sills ina plane below said center sills and" forming struts for said holsters, said draft sills having integral inwardly and outwardly disposed upper flanges','draft sillssto'ps secured to said' upper flanges at each side of the holster, relatively vertical webs and outwardly disoc disposed s ,fingv nieaiis passingthrough said center sills and'said'lower anges.
